Google Index: keep track of how many of your pages are in Google’s index and how we understand their content: you can monitor the overall indexed counts for your site (Index Status), see what keywords we’ve found on your pages (Content Keywords), or request to remove URLs from the search results.

Search Traffic: check how your pages are doing in the search results — how people find your site (Search Queries), who’s recommended your site (Links to Your Site), and see a sample of pages from your site that have incoming links from other internal pages.

Account-level administrative tasks now accessible from the Settings menu

Account-level admin tasks such as setting User permissions, Site Settings, and Change of Address are now grouped under the gear icon in the top right corner so they’re always accessible to you:

This is the list of items as visible to site owners, “full” or “restricted” users will see a subset of these options. For example, if you're a “restricted” user for a site, the "Users & Site Owners" menu item will not appear.

New Search Appearance pop-up

Beginner webmasters will appreciate the new Search Appearance pop-up, which can be used to visualize how your site may appear in search and learn more about the content or structure changes that may help to influence each element:

To access the pop-up window, click on the question mark icon next to the Search Appearance menu in the side navigation.

It includes the essential search result elements like title, snippet and URL, as well as optional elements such as sitelinks, breadcrumbs, search within a site, event and product rich snippets, and authorship information.

We hope the new navigation makes it easier for you to make the most of Webmaster Tools. As always, if you have additional questions, feel free to post in the Webmaster Help Forum.
